If I am not mistaken you have to create a partition on the drive before you can use "pvcreate /dev/sda1". If you would like to get rid of the /run/lvm/lvmetad.socket error just start lvm with "service lvm start". I still get the error when starting up but it still works. I used your first link to do a full encrypted secure boot install of Gentoo. (https://wiki.gentoo.org/wiki/Sakaki%27s_EFI_Install_Guide/Preparing_the_LUKS-LVM_Filesystem_and_Boot_USB_Key). It works like a charm. If you don't want to use a USB key to boot every time make sure you make a small partition on the drive to hold all the information for your encryption and secure boot files. I made that mistake and it took a while to fix. Hope this helps you. -- Willie Matthews matthews.willi...@gmail.com (702) 659-9966
